Uvavanyo lokuxhathisa umhlaba

Ibinzana elithi "ukumelana komhlaba" ligama elichazwe kakuhle. Kwimigangatho ethile (njengamanqanaba okhuseleko kwizixhobo zekhaya), kubhekisa ekuxhathisweni kwesiseko ngaphakathi kwezixhobo, ngelixa kwimigangatho yoyilo (njengakwikhowudi yoyilo), kubhekisa ekuchazeni konke isixhobo sokwenza izinto. Into esithetha ngayo ngokubhekisele ekuxhathisweni kwesiseko ngaphakathi kwezixhobo, oko kukuthi, ukuxhathisa komhlaba (okwabizwa ngokuba yimigangatho yokhuseleko yemveliso, ebonisa izixhobo ezibonakalayo zezixhobo. ukumelana phakathi kwe-wiminals. Umgangatho jikelele ucacisa ukuba oku akufuneki kube ngaphezulu kwe-0,1.

Ukuchaswa komhlaba kuthetha ukuba xa ukufunyanwa kwesixhobo sombane kuyasilela, iindawo ezifikeleleka ngokulula ezinje ngendawo ebiyelwe yombane enjalo inokuhlawuliswa, kwaye ukhuseleko oluthembekileyo luyafuneka ukuze kuqinisekiswe umsebenzisi wesixhobo sombane. Ukuxhathisa okukhohlakeleyo sisibonisi esibalulekileyo ukulinganisa ukuthembeka kokhuseleko lombane lokhuselo.

Ukunganyangeki komgangatho kungalinganiswa nge-tester engachanekanga. Ukususela oko ukuxhathisa komhlaba kuncinanana kakhulu, ihlala kumashumi ee-milliohms, kuyimfuneko ukusebenzisa umlinganiselo-wimine wokuphelisa ukunganyangeki konxibelelwano kunye nokufumana iziphumo ezichanekileyo. Umhloli wokuphikisana komhlaba udityaniswe ngoncedo lovavanyo lovavanyo, isekethe yovavanyo, isalathiso kunye nesekethe yealam. Uncedo lwamandla lovavanyo luvelisa uvavanyo lwe-AC (okanye i-10A), kwaye iSekefi yeSikhombiso iyakhuthaza kwaye iguqule isiginali efunyanwa sisixhobo esiphantsi kovavanyo, esiboniswa sisibonisi. Ukuba ukungqubana komhlaba okulinganiswa kuyinto enkulu kunexabiso lealam (0.1 okanye 0.2), isixhobo siyakuqala isivusi esikhathi.

Ukuchasana kweNkqubo yokuHlala

Xa inkqubo-i-tester elawula ukumelana nokungaxhathisi, iklip yovavanyo kufuneka ikhutshwe kwindawo yoqhagamshelo kumphezulu wenxalenye efikelelekayo. Ixesha lovavanyo akukho lula ukuba lide kakhulu, ukuze singatshisi umbane wovavanyo.

Ukulinganisa ngokuchanekileyo ukungavisisani, iingcingo ezimbini ezityebileyo (ii-wimi ze-voires) kwi-clip yovavanyo kufuneka isuswe kwi-tertage yesixhobo, ithathelwe indawo kunye nezinye izinto eziphakathi Ikliphu yovavanyo yokuphelisa ngokupheleleyo impembelelo yokunganyangeki konxibelelwano kuvavanyo.

Ukongeza, i-tesster yokuchasana nokuchasana nokuchasana nokuchasana nokuchasana nokuchasana nokulinganisa ukunganyange konxibelelwano lwabafowunelwa ohlukeneyo (abafowunelwa) ukongeza ekunciphiseni ukumelana nokunganyangeki.

Izixhobo ze-Merrick's HORD 'UMGAQO-NKQUBO WOKUHLAZIYA I-RK930Olona vavanyo lude lwangoku yi-30a;Rk9330aOlona vavanyo lude lwangoku yi-40a;Rk930bIziphumo eziphezulu zangoku ze-60a; ngovavanyo lokungaxhathisa ubunkunkqele, phantsi kwemijikelezo eyahlukeneyo, umda ophezulu wokuchaswa kovavanyo ubalwa ngolu hlobo lulandelayo:

Xa ukungachanekanga okubaliweyo R mkhulu kunexabiso lokuchasana ne-tester, thatha ixabiso eliphezulu lokuxhathisa.

Zeziphi izibonelelo zenkqubo yomhlaba wokuchasana nomhlaba?

Umhlaba ofanelekileyo wokuxhathisa i-tester genererator ye-Sine ilawulwa ikakhulu yi-CPU ukuvelisa i-SPU ukuvelisa i-SPU ye-SPU, kwaye ukugqobhoza i-gesorm yayo ingaphantsi kwe-0.5%. I-SIne ye-SIne esemgangathweni ithunyelwe kwisekethe ye-Amplimidier ye-Amunidition yamandla, kwaye ke ikhutshelwe ngaphandle kwendawo yokuphuma kwangoku. Imveliso yangoku igqitha ngokuguqula okwangoku. Ukulungiswa, ukulungiswa, ukucoca, kunye ne-A / D Inguqu ithunyelwa kwi-CPU yokubonisa. Ukulungiswa kwe-voltage, ukulungiswa, ukucoca, kunye nokuguqulwa kwe-A / D kuthunyelwa kwi-CPU, kwaye ixabiso lokuchaswa elilinganayo libalwa yi-CPU.

Umhlaba ofanelekileyo womhlaba wokuxhathisaXa kuthelekiswa nomsebenzi we-voltage wemveli yohlobo lokuthintela umhlaba, unezibonelelo zilandelayo:

I-1. Ukuhlala kwangoku komthombo; Cwangcisa okwangoku i-25A, kuluhlu lovavanyo lolu ngcelele lwemiTyelo, ngexesha lovavanyo, imveliso yangoku yeTester yi-25a; Iziphumo zangoku azitshintshi ngomthwalo.

2. Imveliso yangoku yeNkqubo yokuchasana neNkqubo yokuchasana nokuchasana nokuchasa i-tister engachaphazeli kukuvota. Kumthetho wevolthi ye-voltage yemveli yohlobo lokuthintela i-turter, ukuba amandla othusulo atshintsha, iziphumo zayo ezikhoyo ziya kutshintsha nayo na; Lo msebenzi wokuchasana nenkqubo yokuchasana nomhlaba ungafezekiswanga ngumlawuli wevolthi

3.I-RK7305 i-subster yokuphononongwaUmsebenzi wokulinganisa wesoftware; Ukuba iziphumo zangoku, zibonisa ukunganyangeki kwangoku kunye nokuvavanya i-tester igqitha kuluhlu olunikezwe kwincwadana yemigaqo, emva koko umsebenzisi unokukwazi ukuhambisa umlondolozi wezindlu zomsebenzi.Rk933 uthothoInokulungelelaniswa ngokuzenzekelayo kwaye ayichaphazeleki yindalo

4.Imveliso i-frequency yangoku iyahluka; rk930,Rk9330a,Rk930bImveliso yangoku ye-tesster yokuchasana nokuchasana ne-tespring ineendlela ezimbini zokukhetha kuzo: 50hz / 60hz, ezinokuhlangabezana neemfuno zovavanyo ezahlukeneyo.

Ukuvavanywa kokusebenza kokhuseleko kwezixhobo zekhaya

1. Uvavanyo lokunganyangeki

Ukunyangwa kokunganyangwa kwezixhobo zombane zekhaya yenye yeempawu ezibalulekileyo zokuvavanya umgangatho wokufakelwa kwabo. Ukunganyangeki kwe-inseza kubhekisa ekuchanyoni phakathi kwenxalenye yenxalenye yekhaya kunye nenxalenye yentsimbi engaphili. Ngophuhliso olukhawulezileyo lweshishini lokwenza izixhobo kunye nokwanda okukhulu kweemveliso, ukuqinisekisa ukhuseleko lwabasebenzisi, iimfuno zomgangatho wokufakelwa izixhobo zombane zekhaya ziya zingqongqo ngakumbi kwaye zingqongqo ngakumbi.

Indlela yokuHlala kwiMisebenzi yokuHlala

I-1.

2. Khetha i-voltage esebenzayo kwaye ucofe iqhosha le-voltage elifunekayo;

3. Khetha ixabiso lealam;

4. Khetha ixesha lovavanyo (kudidi lokubonisa lwedijithali, uhlobo lwesalathiso alunawo lo msebenzi);

5. I-infinitity yesikolo (); (Rk2681 uthotho unokuxhasa)

I-6. Ukwenzela ukulinganisa okuninzi, qhagamshela umtya wokulinganisa oxhonywe kwisiphelo sokulinganisa, kwaye ulungelelanise i-polibemeter epheleleyo ye-Potendameter ukuze i-pointer ichaza amanqaku apheleleyo.

7. Qhagamshela into elinganayo kwisiphelo sokulinganisa kwaye ufunde ukunyangwa kokufakwa.

Izilumkiso zokuvavanya ukufundela

1. Ifanele ijonge ngokupheleleyo ngaphambi kokulinganisa ukuqhuba umswakama kumatshini, ngakumbi kwimozulu enomswakama ngexesha lemvula emazantsi.

2. Xa ukulinganisa i-interfation yezixhobo zombane ezisebenzayo, izixhobo kufuneka zikhutshwe kwindawo yokubaleka kuqala, kwaye umlinganiso kufuneka wenziwe ngokukhawuleza kwixabiso elilinganayo lokuchaphazeleka ukuqinisekiswa kwindawo yokuthambisa.

3. Isixhobo sokulinganisa ngombane kufuneka sibe kwimeko engasebenziyo, kwaye utshintsho lwesixhobo sokutshintsha kufuneka sibe semgangathweni ukulinganisa i-inshonter, kunye nesekethe okanye izinto ezingahambelaniyo nenxalenye yovavanyo kufuneka zikhutshiwe ngexesha lomlinganiso .

4. Ukwenzela ukuthintela ixabiso lemilinganiselo yokuchaphazeleka kukuntywila okungalunganga kwe-wire, i-cire yokuxhumanisa i-wire ye-wiasi kufuneka itshekishwe rhoqo kwaye ayijiki.
